I believe insecurity is good for the shooting process. When you are out in the world with your digital camera and see something, you raise the camera, frame, and make a photograph. Nine times out of ten, you will look at the screen and respond to what you see previewed there and maybe try again. You might repeat this process three or four times before you «see» the result you want or expect on the screen. Then you move on.
When shooting with film, obviously you don’t have the benefit of seeing the results immediately, so you work with some degree of insecurity, having no idea if you «got it». Actually, the thought of «I got it» isn’t part of the equation at all. The instinct is more to stay within the relationship you established when you responded to something in the first place. You keep working, shooting, and keep trying as many variations as your attention allows. Your attention is not continuously shifting between the world and your tools.
I was brought up with film, so to speak; therefore, it’s been natural for me to adapt a similar opus operandi when shooting digital. What I have noticed in my own process is that photographs that interest me on my contact sheets or in the editing of the shoot later on are often far from what had grabbed my attention initially. Most are the seventh, eight or later variation into the investigation.
With this in mind, you should ask yourself if, by being able to look at your results immediately, you are just confirming what you immediately responded to and capturing what you expect? Or are you actually using the «preview» as a tool to keep working and to discover something transcendent, beyond your expectation? There is capacity for both to happen. You just need to avoid the feeling of self-satisfaction that disrupts the shooting and results in only the former and not the latter.
Another argument for not looking at the preview screen during the shooting process is the fact that you take your eyes off the subject when doing so. You might actually miss the Picture with capital P because of this defocus. (I wrote about this in my post A Curse and a Blessing).
I would like to suggest shooting photographs without looking at them in the moment. Work with a bit of insecurity lingering over your shoulder and see what happens. Put black tape over the preview screen if the draw to look at it is too great—which of course requires that you have a viewfinder to see what you actually shoot (or you can even playing with not seeing what you photograph. You are maybe in for an interesting surprise).
Do you use the preview screen all the time? Or do you take chances and turn it off?
Facts about the photo: It was taken with a Lumix LX7 using a 4.7 zoom setting (the equivalent of a 24 mm full frame lens). Shutter speed: 1/1000 of a second. Aperture: f/2.8. The photo was processed in Lightroom and Photoshop.
